To all whom it may concern Be it known that 1, CHARLES W.Lnw1s, ofChicago, Illinois, have discovered a certain new and useful Improvementin Telephone- 5 Switches, of which the following is a full, clear,

a is the circuit-changer or lever, to which the telephone-line may beconnected. This circuitchan geris mounted upon thecall-box, as shown.The insulated contact pieces or points I) and c 15 are so placed thatwhen the telephone is hung upon the fixed support (I the circuit of thetelephone-line may be directed through the point I), as shown in Fig. 1.0n removing the telephone from its support the lever a is drawn outhori- 2o zontally to the position shown in Fig. 2, and

the circuit of the telephone-line is broken at' pointb and directedthrough the contact-point c. The circuit of the telephone-line may thushe directed automatically through the tele- 25 phone when the telephoneis taken from its support.

In order to hang up the telephone itis necessary to place the ring ofthe telephone in the notch provided on the under side or edge of thecircuit-changer a, and then, by forcing the 0 circuit-changer back,bring the said notch and the ring over the notch provided on the upperedge of the fixed support d. The circuit of the telephone-line may thusbe automatically cutofi'from the telephone and directed through 5 theelectro-magnet of the signal-bell wheu'the telephone is placed upon itssupport.
